Panel antenna array
A system is disclosed for providing a new panel antenna array with enhanced environmental protection, increased reliability and simplified assembly through the incorporation of new array structures. In one embodiment, a panel antenna array system comprises one or more linear arrays having one or more radiating elements for providing antenna transmission and reception; and one or more protection modules to be aligned vertically with each other in a parallel fashion, with each protection module providing protection to one linear array. A mounting bracket further provides a mounting surface to the protection modules.
1. A panel antenna array system comprising:
a plurality of linear arrays of one or more linear array elements that provide antenna transmission and reception;
a corresponding plurality of substantially tubular protection modules disposed substantially parallel to each other, each protection module including an associated one of the associated linear arrays disposed therein, the protection modules fixedly spaced apart at a predetermined spacing that provides a resonant frequency for radio transmission and reception;
a mounting bracket with a mounting surface for receiving the protection modules joined thereto; and
one or more radio frequency (RF) modules immediately attached to the mounting bracket via antenna feed points using an internal cable for providing one or more radio or electrical functions to the linear arrays.
2. The system of claim 1 , wherein each protection module comprises a radome and the linear array is internally slidable with respect to the radome.
3. The system of claim 1 , wherein the protection modules are hollow with opposed open ends.
4. The system of claim 1 , wherein the protection modules each includes a flat surface that is joined to the mounting surface of the mounting bracket.
5. The system of claim 1 , further comprising a centering module that centers and secures the linear array within each associated protection module in an upright fashion, each centering module disposed within the protection module and providing a ground plane for the linear array.
6. The system of claim 5 , wherein the centering module is formed of plastic and includes a surface that is at least partly metal.
7. The system of claim 5 , wherein the centering module includes one or more slots through which an associated linear array element protrudes.
8. The system of claim 1 , further comprising at least one opening serving as a feed point at each protection module for accommodating an antenna feed to feed the linear array.
9. The system of claim 8 , further comprising a structural adhesive sheet joining the protection modules to the mounting bracket, the structural adhesive sheet providing an environmental seal around the feed points.
10. The system of claim 1 , further comprising end caps that cap opposed ends of the protection modules and are interlocked to secure adjacent protection modules together.
11. The system of claim 10 , wherein the end caps are interlocked by at least one of an integral puzzle lock, a plug, and a socket.
12. The system of claim 10 , wherein the protection modules are positioned vertically and the end caps are secured to tops and bottoms of the protection modules, with the end caps at the bottoms each including a value that allows condensed moisture to escape.
13. The system of claim 1 , wherein the protection modules are arranged in a planar fashion.
14. The system of claim 1 , wherein the protection modules are arranged in a circular fashion.
15. The system of claim 1 , wherein each protection module is formed of non-metallic material.
16. The system of claim 1 , wherein the protection modules each include a corresponding grounding plane therein.
17. The system of claim 1 , wherein at least one of the protection modules has non-metallic patches for facilitating air movement therein and preventing moisture intrusion therefrom.
18. The system of claim 1 , wherein each protection module is a hollow member that is an extrusion.
